| The coordination compounds, synthesized with transition metal and Schiff-bases as raw materials, are more and more important for their various structures and extensive uses. The applied foreground of these complexes will be extensive in the field of catalysis, bioactivity and material etc.In this paper, six sulf-schiff bases, 2-formylbenzimidazole condensed with S-methyldithiocarbazate (HLl), 2-formylbenzimidazole condensed with S-benzyl dithiocarbazate (HL2), 2-acetylbenzimidazole condensed with S-methyl dithiocarbazate (HL3), 2-acetylbenzimidazole condensed with S-meth- yldithiocarbazate (HL4), (E)-o- methoxycinnamoylferrocene condensed with S-methyldithiocarbazate (HL5), (E)-o- methoxycinnamoylferrocene condensed with S- benzyl dithiocarbazate (HL6), had been synthesized and characterized. These six Sulf-Schiff bases were used to synthesize the complexes with transition metal ions(Ni2+, Cd2+, Pb2+, Mn2+,Cu2+, Hg2+, Zn2+), and thirty-six complexes obtained.. All of these complexes were characterized by elemental analysis, IR spectra, UV spectra, 1HNMR, molar conductance and cyclic voltammetry. Some of complexes had been determined by X-ray. The molecular structures and the space anarthrias are discussed.On the other hand; We try to synthesize ligands of substituted pyrazoline derivatives (Ln, n=7 to 17) by S-methyldithiocarbazate and S-benzyldithiocarbazate in acidic conditions. Some of this ligands were used to synthesize the complexes with transition metal ions (Cu2+), and five complexes obtained. The crystal of a new complex of CuL72·ClO4 had been determined by X-ray.Seventeen ligands and forty-three complexes, sixty compounds in all were synthesized and fifteen single crystals were obtained. The synthesis reaction mechanisms of the ligand and complexes were presumed by experiment facts. The physiological activities of every compound are being tested and their results will be reported in the future.
